Abstract

In this research, the effects of different stirring speeds on the molten pool flow and the internal flow field of the molten pool were studied by water simulation and numerical simulation. The software ANSYS ICEM, ANSYS FLUENT, and Tecplot 360 were used to model, compute, and post-process, respectively. A physical model made of plexiglass was used to conduct the water simulation experiment. The advantages of vortex smelting reduction were analyzed theoretically and verified by high-temperature experiments. At a stirring speed of approximately 150 rpm, vortex smelting reduction was not only beneficial to the uniform dispersion of the material particles in the molten pool, increasing the reduction reaction rate, but it was also beneficial to the separation of slag and metal. The experimental results confirmed the advantages of vortex smelting reduction, contributing to the recovery of iron in high-iron red mud.

高铁赤泥（铝土矿渣）涡流熔炼还原的优势研究

摘要

本研究通过水模拟和数值模拟研究了不同搅拌速度对熔池流动和熔池内部流场的影响。分别使用ANSYS ICEM、ANSYS FLUENT和Tecplot 360软件进行建模、计算和后处理。使用有机玻璃制成的物理模型进行水模拟实验。从理论上分析了涡流熔炼还原的优点，并通过高温实验加以验证。在150转/分左右的搅拌速度下，涡流熔炼还原不仅有利于物料颗粒在熔池中的均匀分散，提高还原反应速度，而且有利于熔渣与金属的分离。
